I was told once by a party member that, whenever the group has exactly 12 people, there is a 25% experience points bonus to the whole party. However, I can't find anywhere if this is true or not. The only kind of experience bonus I know of is when a party member gives or receives damage from a monster.
If anyone knows about this feature for sure, please share with us in the article. Best regards; --Djyuki 14:28, 3 November 2007 (MDT)
